An object of the invention is the provision of a scraper having a plurality 'o i' carriers adapted to Y be loaded successively until all carriers are full.

Another object of the invention is to mount and lo operate the carriers whereby same may be loaded successively until all carriers are full, said carriers co-operating one with the other to retain the material until ready for discharge.

Y Another object of my invention is the provision 1 in a scraper, of a large capacity carrier comprising a plurality of smaller carriers provided each with a scraper for scraping up material therefor, said carriers cti-operating one with the other to retain the scraped up material until ready for l discharge.

Still another object of the invention is the provision in a scraper, of a main carrier, an auxiliary carrier disposed forwardly of the main'carrier and relative thereto, and a shutter operably disposed forwardly oi the auxiliary lcarrier for selectively opening/and closing the iront end of the auxiliary carrier, said main carrier. auxiliary carrier and shutter co-operating to retain material until ready for discharge.

3o Still otherkobjects, features and advantages of this inventiomwm be apparent to those skilled in the art upon detailed perusal o! the accompanying drawings and the following specifications, wherein I exemplify and describe my invention, but it is to be understood that my inventionis susceptible to modification in the combination, correlation and construction of parts. mem.

bers and yfeatures without departing from the spirit of the invention as denned in the annexed A claims.

In the drawings similar characters oi' reference designate corresponding parts in the several views.

In the drawings: v

Figure 1 is a plansview of my invention in carrying position.

Figure 2 is e side elevation in section or mure l, parts being in carrying position, taken on bro-l ken line 22.

Figure 3 is a fragmentaryside elevation in secs tion taken on broken line 3 2 showing the carriers disposed in discharge position.

Figure 4 is a side elevation in section taken on broken line 3-3 showing the carriers disposed in s position for loading theauxiliary-carrier.

Figure 5 is a side elevation of the scraper showing the carriers disposed in position for loading the main carrier.

Figure 8 is 'a plan view, partly in section, of the large transverse beam in front of the carriers 5 showing the shutter operating mechanism Referring now to the drawings, It designates an axle having rolling supports il Journaled thereon. 10

Disposed on axle il is a beam i2. 'Arms Il are rigid at their rear ends with beam I2 and at their frontends with beam I4 rigid at its opposite ends each with the lower rear portion of a side wan n. Rigid with each or the side walls It is 15 a beam It rigid at their front ends each with an end of the large transverse beam I 1. A beam I8 is rigid at its ends each with the upper rear kportion of a side wall I5. Uprights I9 are rigid at their lower ends each with a beam it and are 20 cross connected at their top ends by a horizontal beam 2l. Vertical posts 2i are rigid at their lower ends with arms I 3 and at their upper ends with beam Il. Rigid at their rear ends with the front side of transverse beam Il are spaced apart 25 members 22, carrying a plurality of relatively spaced pins 2l having journaled thereon rollers 24. Disposed' between members 22 and confined by rollers 24 is a post 25 universally mounted at its lower end at 26 on a pony truck 2l adapted at so 2l for connection to a draft device. Thus, post 2i is supported on rolling supports and members 22 are disposed for vertical movement on the post to determine the position of scraper 29 relative to the ground. Scraper 29 is detachably secured 35 to a wedge shaped transverse beam Ill rigid at its ends each with a side wall il.

Means for causing members 22 to move vertically on post 2i are provided as follows: Secured at its rear end to the upper end of post 25 are 40 arms 3i carrying at their front ends a pin 32 having iournaled thereon sheaves 33. Mounted on the front ends of members 22 is a bracket 34 a pin having journaled thereon sheaves ll in operating alignment wth sheaves Il. Swivelly mounted on bracket 34 is vs direction change sheave lil. Anchored at an end at Il is a cable-Il. Cable 39 thence back and forth about sheaves I3 and 38 and thence about direction change sheave 21, thence to a winding 5o drinn (not shown because conventional). Thus cable Il may be operated to cause members 22 to move vertically on post 25.

The carriers will now be described. A main A bottom 4l, which I shall designate the main carr rier, is disposed rearwardly of wedge shaped beam 3d and pivotally mounted thereon at All by a piano type hinge. The main carrier d@ includes a back plate d2 and brace plates d3. Rigid with the upper edge of the back plate d2 and rigid at its ends each with a brace plate d3, is a beam Id. Thus it is seen that the main carrier l is tiltably disposed behind the scraper 2Q t0 receive material scraped up thereby. Disposed forwardly of the main carrier and scraper@ is the auxiliary bottom 635 which I shall term the auxiliary carrier. Rigid with the auxiliary carrier 45 is a scraper dd. Auxiliary side walls ill are rigid with auxiliary bottom d5, one at each side thereof. Rearwardly extending arms lli are rigid at their iront portions each with an auxiliary side wall 'i'and are pivotally mounted at their rear ends each on a side wall I at t9. lllius, the auxiliary carrier d5 is mounted -on the side walls ib for swinging movement in a vertical plane. A shutter i5@ is disposed forwardly of the a a f= 1f carrier d5 and is provided at its ends each with an arm 5i. Each of the arms Eil are provided with a plate 52 carrying a trunnionvi. Trunnion 53 is journaleci on auxiliary side walls di. 'Ihusthe shutter 5@ is pivotally mounted on side walls il for swinging movement in a vertical plane. Arms 5i are provided at their upper ends each with a pin 563 having journaled thereon sheaves 55.

Cross beam ld rigid with the rear end of the main carrier is provided with two sets of brackets 56 carrying pins 5l having journaled thereon sheaves 58.

cross beam 2o', rigid at its. ends each wim the* upper end of an upright i9, is provided with two sets of brackets 59 carrying pins 6@ having journaled thereon sheaves Si.

Large cross beam il is provided with a plurality of bearings 62 having journaled therein a shaft 63. A driving drum Sd is rigid with shaft 63. A pair of driven drums S5 are rigid with shaft 63.

A pair oi' cables 66 are anchored at an end in any conventional manner to the rigid uprights IS at any convenient point such for example as connections 66' on uprights I9 as shown in Fig. 2 of the drawings and pass thence each, back and forth about a set of relatively arranged sheave block assemblies 58 and 6l, thence back and forth about sheave block assemblies 55 and Il, thence forwardly each to a winding drum b5 to which said cables 66 are anchored.

A cable 6l is anchored to and wound up on a winding drum 6l and passes thence forwardly to and then downwardly about sheave 68 journaled on pin 68 rigid with the front end of a member 22. Cable 68 passes thencedown'wardly thence forwardly about a directionchange sheave 10 to a winding drum not shown (because conven-` tional).

Shutter 50 is providfd with means for raising it to open 'position as follows: Referring now especially to Figures 1, 2 and 6, it will be seen that'the large cross beam ll'is provided with a .tubular member 1I, see Figure 6, attached at l2 to beam I1. Tubular member ll is provided at its opposite end with a plug 13 having an opening therethrough substantially centrally thereof. Encased intubular member 'Il is a coil spring M provided at an end with a plug 15.' Anchor-ed in plug 1i at 8% is `a cable 1t extending thence through the opening in the plug 13, thence about a sheave 'l1 journaled on a pin 'I8 carried by .v

brackets le rigid with beam ill. Beam il also arms 86.

greater carries brackets dii provided with a pin 3l having journaled thereon sheave means 82. Cable i6 passes thence from sheave H to sheave means d2 and is wound thereabout as shown and passed thence downwardly to a connection with shutter 5t as indicated at 83. When the spring 'll is in the position indicated in Figure 6, the shutter 56 would be substantially in the position indicated in Figure 4.

Latch means are provided to releasably secure the main carrier di) against movement toward discharge position until the auxiliary carrier has been discharged, as follows: Side walls i5 are each provided with pins 85, see Figure 5, having pivotaliy mounted thereon an upstanding latch Rigid with the main carrier ,d0 on beam i315, see Figure 1, are brackets 3l having projections de rigid therewith. Referring again to Figure 5, latch arms 86 are adapted as shown tc engage projections 88, and means are provided for disengaging latch arm 86 and projection B3 as follows: Latch arms 86 are provided with projecting pins 39. Control bars 90 are provided with elongated openings 9i in their rear ends adapted to receive projecting pins 89. Arms '39 areV provided with brackets 92 to which the forward end of control bars 9U are pivctally secured at 93. Thus, When'the auxiliary carrier has been raised to the position indicated in Figure 3, control bars 9d will have moved rearwardly until the forward end of the elongated openings 9i have contacted pins 89 and moved latch arms 86 to the disengaged position of Figure 3, after which the main carrier may be moved to discharge position.

Mounted on each'end of shutter 5B and relative to cable @S is a bracket 94 carrying a pin 95 having journaled thereon, a roller 96 the function of which will be described under operation.

Operation of the device will now be described.

Being in the carrying position of Figure 2, to discharge the carriers by causing them to assume the position of Figure 3, cable Gl is operated to unwind cable from winding drum Sli and thus rotate shaft @d and Winding drums 65 in a clockwise direction resulting in winding up cables G6' on winding drums d; The winding up of cables 66 will raise the auxiliary carrier 65 to the position shown in Figure 3 in which position material may spill outwardly therefrom. Raising the auxiliary carrier 45 from the position of Figure 2 to that of Figure 3 will result in moving latch arm 86 from engagement with projection 88 and cable 66 may be further wound up to dispose the main carrier in the discharge position of Figure 3. Thus means is applied to the carriers to ycause theirdischarge successively4 i The device being in the position oi Figure 3, the carriers may be caused to again assume the position of Figure 2 by releasing cable B1 and thus permitting the winding drums tc rotate in aA counter clockwise direction until the carriers again rest in the position of Figure 2.

The device being in the position of Figure 2, it may be caused to assume the loading position of Figure 4 as follows: Cable 6l is again released thus allowing spring 14 to expand, spring 14 being in a compressed state in Figures 2 and 3, resulting in a force being applied to cable 16 to raise the shutter 50. Cable 39 may be operated to lower the front end of the main supporting structure until scraper 46 is in scraping contact with the surface to he rtreated as indicated in Figure 4. `n this position, Figure 4, the scraper is drawn across a surface to be treated until the g5 auxiliary carrier is loaded with material. Cables v il are then woundlup resulting in nrst closing the shutter 5l and subsequently raising the auxiliary carrier to the position of Figure 5, anddcable 39 may at the same time be operated to lower the scraper 29 to the position of Figure 5, `in which ,position the scraper continues to move across the surface to be treated until the main carrier is loaded, at which point cables 65 may be operated to lower the auxiliary carrier to close the opening between scraper 29 and the rear end of the auxiliary carrier Il, and cable 39 may be operated to raise the -scrapers from contact with the surface to be treated and again dispose the loaded device in the position of Figure 2.
